CO2 has Zero IR Transitive Properties and this has been known for decades.
Anthropogenic Global Warming was pointed out as a fraud almost as soon as that half baked theory came out.
The original data which is still used today was a complete fabrication. There is no hockey stick and the scientist who came up with this nonsense theory was originally debunked, until people like The UN and Al Gore got on the gravy train. Now Billions of taxpayer dollars are flushed down the toilet on this nonsense.
The only reason people still talk about Global Warming is because Marxist Fascists Globalists like DemNazis realized they could use it to push for more Goverment Control over various Nation's Economies. So it's never gong away because it is a good vehicle to gain power over people's lives, if not entire nations.
This is why Satanic Treaties like The Paris Accords were formed. It's nothing but a stepping stone to a 666 New World Order.
